Safety information
Before mounting or operating the outboard motor, read this entire manual. Reading it should give you an understanding of the motor and its operation.
Before operating the boat, read any own- ers or operators manuals supplied with it and all labels. Be sure you understand each item before operating.
Do not overpower the boat with this out- board motor. Overpowering the boat could result in loss of control. The rated power of
the outboard should be equal to or less than the rated horsepower capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer.
Do not modify the outboard. Modifications could make the motor unfit or unsafe to use.
Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use.
Never operate after drinking alcohol or tak- ing drugs. About 50% of all boating fatali- ties involve intoxication.
Have an approved personal flotation de- vice (PFD) on board for every occupant. It is a good idea to wear a PFD whenever boating. At a minimum, children and non- swimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating condi- tions.
Gasoline is highly flammable, and its va- pors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel be- fore starting the engine.
This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain dam- age or death when inhaled. Symptoms in- clude nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilat- ed. Avoid blocking exhaust outlets.
Check throttle, shift, and steering for prop- er operation before starting the engine.
Attach the engine stop switch lanyard cord to a secure place on your clothing, or your arm or leg while operating. If you acciden- tally leave the helm, the cord will pull from

the switch, stopping the engine.
Know the marine laws and regulations where you will be boatingand obey them. For basic boating rules, see Rules of the road on page 5.
Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather.
Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you re- turn.
Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat han- dles under the different boating conditions you may encounter. Operate within your limits, and the limits of your boat. Always operate at safe speeds, and keep a careful watch for obstacles and other traffic.
Always watch carefully for swimmers dur- ing the engine operation.
Stay away from swimming areas.
When a swimmer is in the water near you shift into neutral and shut off the engine.
Do not illegally discard empty containers used to replace or replenish oil. For the correct processing of empty containers, consult the dealer where you purchased the oil.
When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilt oil. Never pour oil with- out using a funnel or similar device. If nec- essary, verify the necessary replacement procedure with the dealer.
Never illegally discard (dump) the product. Yamaha recommends consulting the deal- er on discarding the product.

Basic boating rules (Rules of the road)
Just as there are rules which apply when you are driving on streets and high ways, there are waterway rules which apply when you are driving your boat. These rules are used internationally, and are also enforced by the United States Coast Guard and local agen- cies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water. Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road.
ZMU04435
General information
6
The rules presented here in your Owners Manual are condensed, and have been pro- vided for your convenience only. Consult your local U.S. Coast Guard Auxiliary or De- partment of Motor Vehicles for a complete set of rules governing the waters in which you will be using your boat.
EMU25510
Steering and sailing rules and sound signals
Whenever two vessels on the water meet one another, one vessel has the right-of- way; it is called the stand-on vessel. The vessel which does not have the right-of-way is called the give-way or burdened vessel. These rules determine which vessel has the right-of-way, and what each vessel should do.
Stand-on vessel
The vessel with the right-of-way has the duty to continue its course and speed, except to avoid an immediate collision. When you maintain your direction and speed, the other vessel will be able to determine how best to avoid you.
Give-way vessel
The vessel which does not have the right-of- way has the duty to take positive and timely action to stay out of the way of the Stand-On vessel. Normally, you should not cross in front of the vessel with the right-of-way. You should slow down or change directions brief- ly and pass behind the other vessel. You should always move in such a way that the operator of the other vessel can see what you are doing.
The general prudential rule
This rule is called Rule 2 in the International Rules and says, In obeying and construing these rules due regard shall be had to all dangers of naviga- tion and collision, and to any special circum-
stances, which may render a departure from the above rules necessary in order to avoid immediate danger. In other words, follow the standard rules ex- cept when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become Give-Way ves- sels.
EMU25520
Rules when encountering vessels
There are three main situations which you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed:
Meeting:
(you are approaching another ves- sel head-on)
Crossing:
(you are traveling across the oth- er vessels path)
Overtaking:
(you are passing or being passed by another vessel) In the following illustration, your boat is in the center. You should give the right-of-way to any vessels shown in white area (you are the Give-Way vessel). Any vessels in the shad- ed area must yield to you (they are the Give- Way vessels). Both you and the meeting vessel must alter course to avoid each other.
Meeting
If you are meeting another power vessel head on, and are close enough to run the risk of collision, neither of you has the right-of-
General information
7
way! Both of you should alter course to avoid an accident. You should keep the other ves- sel on your port (left) side. This rule doesnt apply if both of you will clear one another if you continue on your set course and speed.
Crossing
When two power driven vessels are crossing each others path close enough to run the risk of collision, the vessel which has the oth- er on the starboard (right) side must keep out of the way of the other. If the other vessel is on your right, you must keep out of its way; you are the Give-Way vessel. If the other vessel is on your port (left) side, remember that you should maintain course and direc- tion, provided the other vessel gives you the right-of-way as it should.
Overtaking
If you are passing another vessel, you are the Give-Way vessel. This means that the other vessel is expected to maintain its
course and speed. You must stay out of its way until you are clear of it. Likewise, if an- other vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you.
EMU25530
Other special situations
There are three other rules you should be aware of when driving your boat around oth- er vessels.
Narrow channels and bends
When navigating in narrow channels, you should keep to the right when it is safe and practical to do so. If the operator of a power- driven vessel is preparing to go around a bend that may obstruct the view of other wa- ter vessels, the operator should sound a pro- longed blast on the whistle (4 to 6 seconds). If another vessel is around the bend, it too should sound the whistle. Even if no reply is heard, however, the vessel should still pro- ceed around the bend with caution. If you navigate such waters with your boat, you will need to carry a portable air horn, available from local marine supply stores.
Fishing vessel right-of-way
All vessels which are fishing with nets, lines or trawls are considered to be fishing ves- sels under the International Rules. Vessels with trolling lines are not considered fishing vessels. Fishing vessels have the right-of- way regardless of position. Fishing vessels cannot, however, impede the passage of other vessels in narrow channels.
Sailing vessel right-of-way
Sailing vessels should normally be given the right-of-way. The exceptions to this are: 1. When the sailing vessel is overtaking
the power-driven vessel, the power-driv- en vessel has the right-of-way.
2. Sailing vessels should keep clear of any fishing vessel.
General information
8
3. In a narrow channel, a sailing vessel should not hamper the safe passage of a power-driven vessel which can navi- gate only in such a channel.
Reading buoys and other markers
The waters of the United states are marked for safe navigation by the lateral system of buoyage. Simply put, buoys and markers have an arrangement of shapes, colors, numbers and lights to show which side of the buoy a boater should pass on when navigat- ing in a particular direction. The markings on these buoys are oriented from the perspec- tive of being entered from seaward (the boat- er is going towards the port). This means that red buoys are passed on the starboard (right) side when proceeding from open wa- ter into port, and black buoys are to port (left) side. When navigating out of port, your posi- tion with respect to the buoys should be re- versed; red buoys should be to port and black buoys to starboard. Many bodies of water used by boaters are entirely within the boundaries of a particular state. The Uniform State Waterway Marking System has been devised for these waters. This system uses buoys and signs with dis- tinctive shapes and colors to show regulato- ry or advisory information. These markers are white with black letters and orange boarders. They signify speed zones, restrict- ed areas, danger areas, and general infor- mation. Remember, markings may vary by geo- graphic location. Always consult local boat- ing authorities before driving your boat in unfamiliar waters.

Fueling instructions
WARNING
EWM00010
GASOLINE AND ITS VAPORS ARE HIGH- LY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and keep
away from sparks, flames, or other sources of ignition.
Stop engine before refueling.
Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat.
Take care not to spill gasoline. If gaso- line spills, wipe it up immediately with
ZMU01708
General information

dry rags.
Do not overfill the fuel tank.
Tighten the filler cap securely after re- fueling.
If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention.
If any gasoline spills onto your skin, im- mediately wash with soap and water. Change clothing if gasoline spills on it.
Touch the fuel nozzle to the filler open- ing or funnel to help prevent electro-
static sparks.
CAUTION:
ECM00010
Use only new clean gasoline which has been stored in clean containers and is not contaminated with water or foreign mat-
ter.
EMU25570
Gasoline
If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel.
Gasohol
There are two types of gasohol: gasohol con- taining ethanol and that containing metha- nol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Yamaha does not recommended gasohol containing methanol because it can cause fuel system damage or engine performance problems.
EMU25660
Engine oil
Use Yamalube 2-M outboard oil. If Ya- malube 2-M is not available, use only anoth- er outboard motor manufacturers factory- brand oil with TC-W3 rating.
CAUTION:
ECM01290
Serious engine damage can result from the use of lower quality oil, including some commonly available oil brands with TC-W3 on their label. To avoid the risk, use only Yamalube 2-M or, if necessary, another outboard motor manufacturers
factory-brand TC-W3 oil.
EMU25700
Battery requirement
CAUTION:
ECM01060
Do not use a battery that does not meet the specified capacity. If a battery which does not meet specifications is used, the electric system could perform poorly or be overloaded, causing electric system
damage.
For electric start models, choose a battery which meets the following specifications.
Recommended gasoline: Regular unleaded gasoline with a min- imum octane rating of 86 (Pump Oc- tane Number) = (R+M)/2
Recommended engine oil: YAMALUBE 2 STROKE OUTBOARD OIL

Battery specifications
NOTE:
The engine cannot be started if battery volt-
age is too low.
EMU25742
Propeller selection
The performance of your outboard motor will be critically affected by your choice of propel- ler, as an incorrect choice could adversely affect performance and could also seriously damage the motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine. Yamaha outboard motors are fitted with pro- pellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate. For a greater operating load, a smaller-pitch propeller is more suit- able as it enables the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller oper- ating load. Yamaha dealers stock a range of propellers, and can advise you and install a propeller on your outboard that is best suited to your ap- plication.
NOTE:
Select a propeller which will allow the engine to reach the middle or upper half of the oper- ating range at full throttle with the maximum boat load. If operating conditions such as light boat loads then allow the engine r/min to rise above the maximum recommended range, reduce the throttle setting to maintain
the engine in the proper operating range.
For instructions on propeller removal and in- stallation, see page 60.
EMU25770
Start-in-gear protection
Yamaha outboard motors or Yamaha-ap- proved remote control units are equipped with start-in-gear protection device(s). This feature permits the engine to be started only when it is in neutral. Always select neutral before starting the engine.

WARNING
EWM00031
Do not overtighten the friction adjuster. If there is too much resistance, it could be difficult to move the remote control lever or throttle grip, which could result in an
accident.
When constant speed is desired, tighten the adjuster to maintain the desired throttle set- ting.
EMU25990
Engine stop lanyard switch
The lock plate must be attached to the en- gine stop switch for the engine to run. The lanyard should be attached to a secure place on the operators clothing, or arm or leg. Should the operator fall overboard or leave the helm, the lanyard will pull out the lock plate, stopping ignition to the engine. This will prevent the boat from running away un- der power.
WARNING
EWM00120
Attach the engine stop switch lanyard to a secure place on your clothing, or
your arm or leg while operating.
Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where it could become entan- gled, preventing it from functioning.
Avoid accidentally pulling the lanyard during normal operation. Loss of en- gine power means the loss of most steering control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the
boat to be thrown forward.
NOTE:
The engine cannot be started with the lock
plate removed.
